The face seal is a fundamental design element that creates a closed, isolated breathing space inside the visor. Its precise fit to the helmet shell and the wearer’s face enables the e3000X’s power unit to create a stable positive pressure. It is this positive pressure that actively prevents harmful dusts, fumes and aerosols from entering the breathing zone, which is the basis of TH3 class systems. Even the slightest damage or leakage of this component can degrade the level of protection. Investing in regular seal replacement is a direct investment in maintaining the highest certified level of health protection.

In the Optrel ecosystem, the seal is more than just a barrier. It is designed as an integral part of the air distribution system. Its shape and placement are precisely calculated to direct a stream of clean air in a controlled and even manner, sweeping over the face without causing eye irritation. This design not only ensures a constant supply of oxygen, but also generates a noticeable cooling effect on the forehead, which is invaluable during prolonged work in high temperatures. It’s an investment in comfort that translates into less fatigue and higher concentration throughout the work shift.

As a component in direct contact with the skin, the seal is naturally exposed to sweat, dust and other contaminants of the working environment. Being able to replace it simply and quickly is crucial to maintaining high standards of personal hygiene. Regular replacement prevents the buildup of bacteria, the formation of unpleasant odors and ensures freshness during each use. Taking care of this consumable element is the basis for comfortable and hygienic use of the entire, expensive PAPR system. It is a small expense that provides comfort and prolongs the life of the entire protective kit.
